Endoscopic submucosal dissection for superficial esophageal neoplasms

Endoscopic submucosal dissection(ESD) is currently accepted as the major treatment modality for superficial neoplasms in the gastrointestinal tract including the esophagus.An important advantage of ESD is its effectiveness in resecting lesions regardless of their size and severity of fibrosis.Based on excellent outcomes for esophageal neoplasms with a small likelihood of lymph node metastasis,the number of ESD candidates has increased.On the other hand,ESD still requires highly skilled endoscopists due to technical difficulties.To avoid unnecessary complications including perforation and postoperative stricture,the indications for ESD require careful consideration and a full understanding of this modality.This article,in the highlight topic series,provides detailed information on the indication,procedure,outcome,complications and their prevention in ESD of superficial esophageal neoplasms.

Treatment efficacy of radiof requency ablation of 338 patients with hepatic malignant tumor and the relevant complications

AIM： To investigate the treatment efficacy of radiofrequency ablation （RFA） of hepatic malignant tumor and the relevant complications. METHODS： A total of 338 patients with 763 hepatic tumors underwent ultrasound-guided RFA （565 procedures）. There were 204 cases of hepatic cellular carcinoma （HCC） with 430 tumors, the mean largest diameter was 4.0 cm. Of them, 48 patients （23.5%） were in stages Ⅰ-Ⅱ （UICC Systems） and 156 （76.5%） in stages Ⅲ-Ⅳ There were 134 cases of metastatic liver carcinoma （MLC）, with 333 metastases in the liver, the mean diameter was 4.1 cm, the liver metastases of 96 patients （71.6%） came from gastrointestinal tract. Ninety-three percent of the 338 patients were treated using the relatively standard protocol. Crucial attention must be paid to monitor the abnormal changes in ultrasound images as well as the vital signs of the patients to find the possible hemorrhage and peripheral structures injury in time. The tumors were considered as ablated completely, if no viability was found on enhanced CT within 24 h or at 1 mo after RFA. These patients were followed up for 3-57 too. RESULTS： The ablation success rate was 93.3% （401/430 tumors） for HCC and was 96.7% （322/333 tumors） for MLC. The local recurrence rate for HCC and MLC was 7.9% （34/430 tumors） and 10.5% （351333 tumors）, respectively. A total of 137 patients （40.5%） underwent 2-11 times of repeated ablations because of tumor recurrence or metastasis. The 1st, 2nd, and 3rd year survival rate was 84.6%, 66.6%, and 63.1%, respectively; the survival rate from 48 patients of I-II stage HCC was 93.7%, 80.4%, and 80.4%, respectively. The major complication rate in this study was 2.5% （14 of 565 procedures）, which consisted of 5 hemorrhages, i colon perforation, 5 injuries of adjacent structures, 2 bile leakages, and 1 skin burn. CONCLUSION： RFA, as a minimally invasive local treatment, has become an effective and relatively safe alternativefor the patients of hepatic malignant tumor, even of advanced liver tumor, tumor recurrence, and liver metastases. Knowledge about possible complications and their control may increase the treatment efficacy and help to promote the use of RFA technique.

Neurological complications of hematopoietic cell transplantation in children and adults

Hematopoietic cell transplantation（HCT） is widely performed for neoplastic and non-neoplastic diseases. HCT involves intravenous infusion of hematopoietic progenitor cells from human leukocyte antigen（HLA）-matched donor（allogeneic） or from the patient（autologous）. Before HCT, the patient is prepared with high dose chemotherapy and/or radiotherapy to destroy residual malignant cells and to reduce immunologic resistance. After HCT, chemotherapy is used to prevent graft rejection and graft versus host disease（Gv HD）. Neurological complications are related to the type of HCT, underlying disease, toxicity of the conditioning regimens, immunosuppression caused by conditioning regimens, vascular complications generated by thrombocytopenia and/or coagulopathy, Gv HD and inappropriate immune response. In this review, neurological complications are presented according to time of onset after HCT：（1） early complications（in the first month）-related to harvesting of stem cells, during conditioning（drug toxicity, posterior reversible encephalopathy syndrome）, related to pancytopenia,（2） intermediate phase complications（second to sixth month）-central nervous system infections caused by prolonged neutropenia and progressive multifocal leukoencephalopathy due to JC virus,（3） late phase complications（after sixth month）-neurological complications of Gv HD, second neoplasms and relapses of the original disease.

Postoperative complications after robotic resection of colorectal cancer:An analysis based on 5-year experience at a large-scale center

BACKGROUND As a common gastrointestinal malignancy,colorectal cancer(CRC)poses a serious health threat globally.Robotic surgery is one of the future trends in surgical treatment of CRC.Robotic surgery has several technical advantages over laparoscopic surgery,including 3D visualization,elimination of the fulcrum effect,and better ergonomic positioning,which together lead to better surgical outcomes and faster recovery.However,analysis of independent factors of postoperative complications after robotic surgery is still insufficient.AIM To analyze the incidence and risk factors for postoperative complications after robotic surgery in patients with CRC.METHODS In total,1040 patients who had undergone robotic surgical resection for CRC between May 2015 and May 2020 were analyzed retrospectively.Postoperative complications were categorized according to the Clavien-Dindo(C-D)classification,and possible risk factors were evaluated.RESULTS Among 1040 patients who had undergone robotic surgery for CRC,the overall,severe,local,and systemic complication rates were 12.2%,2.4%,8.8%,and 3.5%,respectively.Multivariate analysis revealed that multiple organ resection(P<0.001)and level III American Society of Anesthesiologists(ASA)score(P=0.006)were independent risk factors for overall complications.Multivariate analysis identified multiple organ resection(P<0.001)and comorbidities(P=0.029)as independent risk factors for severe complications(C-D grade III or higher).Regarding local complications,multiple organ resection(P=0.002)and multiple bowel resection(P=0.027)were independent risk factors.Multiple organ resection(P<0.001)and level III ASA score(P=0.007)were independent risk factors for systemic complications.Additionally,sigmoid colectomy had a lower incidence of overall complications(6.4%;P=0.006)and local complications(4.7%;P=0.028)than other types of colorectal surgery.CONCLUSION Multiple organ resection,level III ASA score,comorbidities,and multiple bowel resection were risk factors for postoperative complications,with multiple organ resection being the most likely.

Does testosterone prevent early postoperative complications after gastrointestinal surgery?

AIM:To investigate the role of sex hormones in the early postoperative complications of gastrointestinal diseases. METHODS:A total of 65 patients who underwent operations for gastric and colorectal diseases(mainly malignant diseases)were included in the study. Peripheral venous blood samples were collected at different times for analysis of estradiol,testosterone and progesterone.The only study endpoint was analysis of postoperative complications. RESULTS:Patients of both sexes were uniform but postoperative complication rate was significantly higher in female patients(P=0.027).There was no significant association of estradiol and progesterone with postoperative complications.Testosterone levels in complicated patients were significantly lower than in uncomplicated patients(P<0.05).Area under the receiver operating characteristic curve showed that a lower value of testosterone was a predictor for higher complication rate(P<0.05),and a lower value oftestosterone at later times after surgery was a better predictor of complications. CONCLUSION:Patients with low testosterone level were prone to higher postoperative complications,which was evident in both sexes.However,further studies are necessary to support this result.

Nomogram for predicting early complications after distal gastrectomy

BACKGROUND Reducing or preventing postoperative morbidity in patients with gastric cancer(GC)is particularly important in perioperative treatment plans.AIM To identify risk factors for early postoperative complications of GC post-distal gastrectomy and to establish a nomogram prediction model.METHODS This retrospective study included 131 patients with GC who underwent distal gastrectomy at the Second Hospital of Shandong University between January 2019 and February 2023.The factors influencing the development of complications after distal gastrectomy in these patients were evaluated using univariate and multivariate logistic regression analysis.Based on the results obtained,a predictive nomogram was established.The nomogram was validated using internal and external(n=45)datasets.Its sensitivity and specificity were established by receiver operating characteristic curve analysis.Decision curve(DCA)analysis was used to determine its clinical benefit and ten-fold overfitting was used to establish its accuracy and stability.RESULTS Multivariate logistic regression analysis showed that hypertension,diabetes,history of abdominal surgery,and perioperative blood transfusion were independent predictors of postoperative complications of distal gastrectomy.The modeling and validation sets showed that the area under the curve was 0.843[95%confidence interval(CI):0.746-0.940]and 0.877(95%CI:0.719-1.000),the sensitivity was 0.762 and 0.778,respectively,and the specificity was 0.809 and 0.944,respectively,indicating that the model had good sensitivity and specificity.The C-indexes of the modeling and validation datasets were 0.843(95%CI:0.746-0.940)and 0.877(95%CI:0.719-1.000),respectively.The calibration curve(Hosmer Lemeshow test:χ^(2)=7.33)showed that the model had good consistency.The results of the DCA analysis indicated that this model offered good clinical benefits.The accuracy of 10-fold cross-validation was 0.878,indicating that the model had good accuracy and stability.CONCLUSION The nomogram prediction model based on independent risk factors related to postoperative complications of distal gastrectomy can facilitate perioperative intervention for high-risk populations and reduce the incidence of postoperative complications.

Clinical application of reserved gastric tube in neuroendoscopic endonasal surgery for pituitary tumor

BACKGROUND The neuroendoscopic approach has the advantages of a clear operative field,convenient tumor removal,and less damage,and is the development direction of modern neurosurgery.At present,transnasal surgery for sphenoidal pituitary tumor is widely used.But it has been found in clinical practice that some patients with this type of surgery may experience post-operative nausea and vomiting and other discomforts.AIM To explore the effect of reserved gastric tube application in the neuroendoscopic endonasal resection of pituitary tumors.METHODS A total of 60 patients who underwent pituitary adenoma resection via the endoscopic endonasal approach were selected and randomly divided into the experimental and control groups,with 30 in each group.Experimental group:After anesthesia,a gastric tube was placed through the mouth under direct vision using a visual laryngoscope,and the fluid accumulated in the oropharynx was suctioned intermittently with low negative pressure throughout the whole process after nasal disinfection,during the operation,and when the patient recovered from anesthesia.Control group:Given the routine intraoperative care,no gastric tube was left.The number of cases of nausea/vomiting/aspiration within 24 h post-operation was counted and compared between the two groups;the scores of pharyngalgia after waking up,6 h post-operation,and 24 h postoperation.The frequency of postoperative cerebrospinal fluid leakage and intracranial infection were compared.The hospitalization days of the two groups were statistically compared.RESULTS The times of postoperative nausea and vomiting in the experimental group were lower than that in the control group,and the difference in the incidence of nausea was statistically significant(P<0.05).After the patient woke up,the scores of sore throat 6 h after the operation and 24 h after operation were lower than those in the control group,and the difference was statistically significant(P<0.05).The number of cases of postoperative cerebrospinal fluid leakage and intracranial infection was higher than that of the control group,but there was no statistically significant difference from the control group(P>0.05).The hospitalization days of the experimental group was lower than that of the control group,and the difference was statistically significant(P<0.05).CONCLUSION Reserving a gastric tube in the endoscopic endonasal resection of pituitary tumors,combined with intraoperative and postoperative gastrointestinal decompression,can effectively reduce the incidence of nausea,reduce the number of vomiting and aspiration in patients,and reduce the complications of sore throat The incidence rate shortened the hospitalization days of the patients.

Prognostic value of postoperative complication for early recurrence after curative resection of hepatocellular carcinoma

Background: Postoperative complications may adversely affect oncological outcomes. The aim of this study was to evaluate the impact of postoperative complications on early-phase recurrence after curative resection for hepatocellular carcinoma(HCC).Methods: We included 145 HCC patients who underwent initial and curative resection between January2004 and December 2013. Postoperative complications of grade III or higher based on Clavien–Dindo classification were defined as clinically relevant postoperative complications. Recurrence within two years after hepatectomy was defined as early-phase recurrence.Results: Thirty-eight patients(26%) developed postoperative complications. The only predictive factor for postoperative complication was longer operative duration(P = 0.037). The disease-specific survival rate of patients with complication was lower than that of patients without complications(P = 0.015). Earlyphase recurrence was observed in 20/38(53%) patients who suffered postoperative complications and36/107(34%) patients with no complications, which was statistically significant(P = 0.039). Multivariate analysis identified four factors contributing to early-phase recurrence: high serum AFP level(P = 0.042),multiple tumors(P < 0.001), poor differentiation(P = 0.036) and presence of postoperative complication(P = 0.039).Conclusions: Postoperative complication is an independent prognostic factor for early-phase recurrence after curative resection of HCC. Close observation of patients with postoperative complications may be a necessary treatment strategy for HCC.

Epigenetic changes of pituitary tumor-derived transforming gene 1 in pancreatic cancer

BACKGROUND: Pancreatic cancer is a devastating disease with abnormal genetic changes. The pituitary tumor-derived transforming gene (PTTG) is considered to be implicated in the tumorigenesis of cancers when the gene is epigenetically transformed. In this study, we investigated the relationships between aberrant expression and epigenetic changes of the PTTG1 gene in pancreatic cancer. METHODS: We chose 4 cell lines (PANC-1, Colo357, T3M-4 and PancTu I) and pancreatic ductal adenocarcinoma (PDAC) tissues. After using restriction isoschizomer endonucleases (Msp I /Hpa II) to digest the DNA sequence (5'-CCGG-3'), we performed PCR reaction to amplify the product. And RT-PCR was applied to determine the gene expression. RESULTS: The mRNA expression of the PTTG1 gene was higher in pancreatic tumor than in normal tissue. The gene was also expressed in the 4 PDAC cell lines. The methylation states of the upstream regions of the PTTG1 gene were almost identical in normal, tumor pancreatic tissues and the 4 PDAC cell lines. Some (5'-CCGG-3') areas in the upstream region of PTTG1 were methylated, while some others were unmethylated. CONCLUSIONS: The oncogene PTTG1 was overexpressed in pancreatic tumor tissues and verified by RT-PCR detection. The methylation status of DNA in promoter areas was involved in the gene expression with the help of other factors in pancreatic cancer.

Hyperprolactinemia due to pituitary metastasis: A case report

BACKGROUND Pituitary metastasis is an uncommon manifestation of systemic malignant tumors.Moreover,hyperprolactinemia and overall hypopituitarism caused by metastatic spread leading to the initial symptoms are rare.CASE SUMMARY A 53-year-old male patient was admitted to our hospital with complaints of bilateral blurred vision,dizziness,polyuria,nocturia,severe fatigue and somnolence,decreased libido,and intermittent nausea and vomiting for more than 6 mo.During the last 7 d,the dizziness had worsened.Laboratory investigations revealed overall hypofunction of the pituitary gland,but the patient had an elevated serum prolactin level(703.35 mg/mL).Preoperative magnetic resonance imaging revealed a tumor in the sellar region,accompanied by intratumoral hemorrhage and calcification.Thus,transnasal subtotal resection of the lesion in the sellar region was performed.The histopathological and immunohistochemical examinations of the resected lesion revealed metastasis of lung adenocarcinoma to the pituitary gland.Oral hydrocortisone(30 mg/d)and levothyroxine(25 mg/d)were given both pre-and postoperatively.Postoperatively,the clinical symptoms were significantly improved.However,4 mo following the surgery,the patient succumbed due to multiple organ failure.CONCLUSION Hyperprolactinemia is one of the markers of poor prognosis in patients with carcinoma that metastasizes to the pituitary gland.Exogenous hormone supplementation plays a positive role in relieving the symptoms of patients and improving quality of life.

Simultaneous rectal neuroendocrine tumors and pituitary adenoma:A case report and review of literature

BACKGROUND Neuroendocrine tumors(NET)are rare heterogeneous tumors that arise from neuroendocrine cells throughout the body.Acromegaly,a rare and slowly progressive disorder,usually results from a growth hormone(GH)-secreting pituitary adenoma.CASE SUMMARY We herein describe a 38-year-old patient who was initially diagnosed with diabetes.During colonoscopy,two bulges were identified and subsequently removed through endoscopic submucosal dissection.Following the surgical intervention,the excised tissue samples were examined and confirmed to be grade 2 NET.^(18)F-ALF-NOTATATE positron emission tomography-computed tomography(PET/CT)and 68Ga-DOTANOC PET/CT revealed metastases in the peri-intestinal lymph nodes,prompting laparoscopic low anterior resection with total mesorectal excision.The patient later returned to the hospital because of hyperglycemia and was found to have facial changes,namely a larger nose,thicker lips,and mandibular prognathism.Laboratory tests and magnetic resonance imaging(MRI)suggested a GH-secreting pituitary adenoma.The pituitary adenoma shrunk after treatment with octreotide and was neuroendoscopically resected via a trans-sphenoidal approach.Whole-exome sequencing analysis revealed no genetic abnormalities.The patient recovered well with no evidence of recurrence during follow-up.CONCLUSION ^(18)F-ALF-NOTATE PET/CT and MRI with pathological analysis can effectively diagnose rare cases of pituitary adenomas complicated with rectal NET.

Comparative study of curative effect between neuroendoscopy and microscope via order nasal sphenoid sinus approach of pituitary adenoma resection

Objective:To study the effect and prognosis and serological parameters between neuroendoscopy and microscope via order nasal sphenoid sinus approach of pituitary adenoma resection.Methods:120 patients with pituitary adenoma were admitted in our hospital from January 2015 to January 2018, and were divided into two groups: observation group and control group, 60 cases in each group. The patients in the observation group were treated with pituitary tumor resection via the order nasal sphenoid sinus approach under neuroendoscopy, and the patients in the control group were treated with the pituitary adenoma resection under the microscope. The effects of operation on clinical efficacy, complications, prognosis, hormone level and visual function were compared between the two groups.Results: The total resection rate was significantly higher in the observation group than in the control group, and the recurrence rate, intraoperative bleeding, operative time and postoperative hospital stay were significantly lower than those in the control group, with statistically significant. The levels of ACTH, TSH and HGH in the two groups decreased significantly 2 weeks after operation, and the levels of hormone in the observation group were significantly lower than those in the control group 2 weeks after operation. The levels of NE, E, ATⅡ and R increased significantly in both groups, and the levels of stress indexes in the observation group were significantly lower than those in the control group. 2 weeks after operation, the MD, PSD, VFI of the two groups was significantly higher than that of the pre-operation group. The MD, VFI of the observation group was significantly higher than that of the control group, and the PSD was significantly lower than that of the control group. The main complications were cerebrospinal fluid leakage, urinary avalanche, intracranial hemorrhage and infection. The overall incidence of the patients in the observation group was significantly lower than that in the control group. Conclusion: The curative effect of pituitary adenoma resection via transsphenoidal approach by neuroendoscopy is significantly better than that of microsurgery. Neuroendoscopic surgery can significantly reduce intraoperative bleeding and stress response, thereby reducing the incidence of complications and contributing to the prognosis.
